DHEA is essentially a fairly powerful hormone. And most people take way too much throwing off the body's internal balance. This is a perfect dose for me (and likely most people) and relatively hard to find. DHEA in this dose has lots of benefits.

Even my local "mega" and "super" supplement stores don't stock a single organic whey powder. This stuff mixes fairly well, tastes decent, and doesn't have any signficant carbs or nasty artificial sweeteners. The only downside is it's a bit expensive per pound. But given what they feed some dairy cattle it might be worth the price premium. Some whey comes from China and you have to REALLY wonder about some of that stuff given the whole melamine debacle.

A lot of "sports protein" bars are loaded up with nasty refined sugars, tons of glucose (to make the carb numbers look better), and/or a bunch of hard to pronounce ingredients. Others have nasty soy protein. These have a decent ingredient list and claim to have a low glycemic index. They also taste pretty good.
The bad news is they still have a lot of carbs. And I'm not so sure they're as low glycemic as claimed as I clearly "crash" an hour or so after eating one. I tend to eat one half at a time to help avoid the carb rush. But they make a decent meal replacement bar--especially if you're not worried about carbs.

These have a good combination of sleep aids without overdosing on melatonin (a common flaw with many sleep aids, it's a hormone and requires caution--even 1 mg is questionable and many sleep formulas have even higher amounts). They help me fall asleep and stay sleeping better than anything else I've tried.

I was on the Clean diet and the book recommended liver protection supplements but I'm not sure products like this really do much good? It's hard to say. Most people (including me) use them while altering other habits in their life such as diet, drinking, sleep, etc. so it's hard to say any benefits are from this product and not the other changes.

The manufacture has combined such a huge number of different things it's probably impossible to know how they all interact. Some might even cancel each other out. This supplement seems over priced for the relatively weak benefit I got from it. I think there are better engineered mental supplements that cost less per dose. New Chapter seems like psuedo-science to me.
